Time for a Little Fun, Make an Alien

Hey, I thought this might be an interesting little activity you guys can do on the side when you get bored. All you need for this activity is a 6
sided die, pen or pencil, and a piece of paper to write down your answers.
Please feel free to go through this and then if you want go ahead and post your own results here.

Purpose:
This activity simulates the random nature of evolution, and explores the possibilities of the forms of alien life.
Audience:
This activity is appropriate for adults, high school and college students, and particularly grade school kids. Older students will sometimes be "too
cool" for this, although most adults get a kick out of it. For very young children, shorten the list of choices, so that they can spend most of their
time drawing and coloring. To answer the questions, the audience should be prepped with some information about the planets...
Activity:
In this activity, you are going to create a form of animal life that might have evolved on a planet (or satellite) that is probably not like Earth.
Rolling a die will simulate the role of chance in the evolution of your extraterrestrial creature. Each roll of the die represents a result of
millions of years of chance variations that were successful in the extraterrestrial's environment.
In your group, roll the die and follow the instructions for the 23 adaptations below. When you are finished, take a minute to talk within your group
about what sort of creature you have created, and what environment it would need.
On your own draw or describe your creature. Give the species a name. Write a paragraph about your creature, addressing the following points:
Describe the environment your creature needs to survive.
Where in our solar system would you be most likely to find such a creature?
What sort of food source might your creature need?
Is your creature alone in its environment? If not, how does it coexist with other species.

1. Skin: If you roll a ... then your creature has ...
1, 2 or 3: scaly skin, like a snake.
4 or 5: mucus covered soft skin, like a slug.
6: leathery skin, like a cow.

2. Openings: People have different openings or holes in their bodies to breathe, get rid of waste, and eat. Some animals, like anemones, use one
opening for several of these purposes. How many openings does your creature have, and what does it use them for?
If you roll a ... then your creature has ...
1 or 2: 1 opening (like a sea anemone)
3 or 4: 2 openings (like an earthworm)
5 or 6: 3 openings (like a frog)

3. Body Shape: If you roll a ... then your creature ...
1, 2, 3 or 4: is longer than it is wide.
5 or 6: has some other shape.

4. Segments: If you roll a ... then your creature ...
1, 2 or 3: is divided into segments (like a centipede). Go to 5: appendages for segments.
4, 5, or 6: has no segments (like a toad). Go to 6: appendages for no segments.

5. Appendages for Segments: Roll one die two times and add the numbers together to find the number of segments your creature has. Your creature has
two appendages on each segment, so multiply by two to get the number of appendages. (example: 3 segments X 2 = 6 appendages) Go to 7: Hard Parts.

6. Appendages for No Segments: Roll one die. This is the number of appendages your organism has. Go to 7: Hard Parts.

7. Hard Parts: If you roll a ... then your creature ...
1, 2 or 3: has hard parts on the outside of its body (like a lobster). Go to 8:Outside hard parts.
4 or 5: has hard parts on the inside of its body (bones, like you). Go to 9: Large Sizes.
6: has no hard parts. It gets around by wiggling (like a worm). Go to 10: Small sizes.

8. Outside Hard Parts: If you roll a ... then your creature ...
1 or 2: has a hard shell (like a snail). Go to 10: Small sizes.
3 or 4: has a protein, armor-like covering (like a beetle). It must shed this covering in order to grow. Go to 10: Small sizes.
5 or 6: has a protein, shell-like covering (like an insect). It doesn't need to shed this covering to grow. Go to 9: Large sizes.

9. Large sizes: Roll one die for the range of your creature's weight.If you roll a ... then your creature weighs between ...
1: 6-9 pounds, like a cat.
2: 10-49 pounds, like a bobcat.
3: 50-99 pounds, like a German Shepherd.
4: 100-199 pounds, like an alligator.
5: 200-999 pounds, like a pig.
6: 1,000-100,000 pounds, like a dinosaur.
Go to 11: Feeding the Cells of Large Animals.

10. Small sizes: Roll one die for the range of your creature's weight.If you roll a ... then your creature weighs between ...
1 or 2: 0 and 1 pound, like a mouse.
3 or 4: 1 and 2 pounds, like a rat.
5 or 6: 2 and 5 pounds, like a chicken.
Go to 12: Feeding the Cells of Small Animals.

11. Feeding the Cells of Large Animals: We take in air and food from our environment. Our blood absorbs oxygen from the air and nutrients from the
food. Our hearts pump the blood through our bodies, carrying the oxygen and nutrients to every cell. Roll one die to find out how your creature gets
oxygen and nutrients to its organs.
If you roll a ... then your creature ...
1, 2, 3 or 4: has one heart to pump blood, like you.
5 or 6: has multiple hearts, like an octopus. Roll one die for the number of hearts.
Go to 13: Moving Around.

12. Feeding the Cells of Small Animals: Like people, earthworms take in oxygen and food from their environment. The oxygen and food nutrients are
absorbed in the worm's blood. Five small hearts pump blood through the body to give oxygen and nutrients to all the cells. Other small animals get
food and oxygen to their cells in different ways. Roll one die to find out how your small animal gets oxygen and nutrients to its cells. If you roll a
... then your creature ...
1 or 2: has oxygen and food in the blood, and only one heart, like a mouse.
3 or 4: has oxygen and food in the blood, and multiple hearts, like an earthworm. Roll one die for the number of hearts.
5: has oxygen and food in the blood, which sloshes around inside, bathing all cells, like a lobster.
6: is only a few cells thick. It absorbs oxygen and food directly through its skin, and has no blood, like a flatworm.
Go to 13: Moving Around

vibrations? If you roll a ... then your creature ...
1, 2 or 3: has organs, like ears, to sense vibrations in the air (like a mole) or in the water (like a dolphin).
4, 5 or 6: has small hairs scattered over its body to sense vibrations in the air or water, like some fishes or spiders.

15. Chemical Senses: People have sensors that detect chemicals in the air, food or water. THey are in your nose and tongue, but chemical sensors are
not always in noses or tongues. Spiders have them on the soles of their feet. Where are your creature's sensors located? If you roll a ... then your
creature's sensors are located ...
1, 2 or 3: in one place, like a spider.

Go to 27.
4, 5 or 6: is sexual. Your creature reproduces by sex (two or more organisms share their adaptations, and make babies a little different from
themselves), like cats.

24. Sexual Reproduction: If you roll a ... then your creature's species ...
1 or 2: has two sexes: A and B. Every individual has only one sex, like people and other mammals.
3 or 4: has two sexes: A and B. Every individual has both sexes, but two individuals are required to mate, like earthworms.
5 or 6: has three sexes: A, B and C. Every individual has one sex, and three individuals are required to mate. There are no examples like this on
